QUESTION
I'm using Delphi 5, and I want to display the results of a MySQL query in a cxGrid. I have the cxGrid, cxGridLevel, and cxGridDBTableView set up the way they default to when added to a form. The DataController.DataSource for the cxGridDBTableView is a TDataSource named DSNewKits with its DataSet set to a tMySQLQuery named NewKitsQry.
When it's time to display the data, I set the Enabled property of DSNewKits to false, run the Close method of NewKitsQry, then set the Enabled property of DSNewKits to true, set the SQL.Text property of NewKitsQry, and run the Open method NewKitsQry. I then have a message dialog display the number of results in the query, and there are 408, so I know the query is working properly. The grid displays rows & columns with lines in between, no "No data to display" message, but all the cells are blank.
I have tried doing these steps in a different order, commenting out some of them, etc., but nothing causes the data to display. I'm sure I'm missing something simple &/or obvious, but I was unable to find an example online. Thank you for any help you can give!
(Edited to include code) Here is my code:

Answered 2020-Aug-20 at 16:57Although the cxGrid is a fine component, the fact that it has so many deeply-nested properties can make it quite daunting to set up a cxGrid from scratch.
I created the example below to show how to create and set up a cxGrid entirely in code so that you can easily see the bare minimum which needs to be done. It uses a TClientDataSet, which is populated in code, to supply the grid's data so that the example is completely self-contained. It would be trivial to adapt it to an existing MySql dataset.

I have a table which including Student's name, course_id and score, the different students may have a different course and different score.
And now I need to output the academic standings for each student, here is the rule for the academic standings:
- If a student takes only one course(count(course_id)=1), he/she will receive ‘Good’ if the score >= 50, and ‘Referral’ if the score < 50;
- If a student takes more than one course (count(course_id)>=2), his/her academic standing would be ‘Probation’ if none of the score >=50, ‘Referral’ if 50% or less of the taken courses are score >=50, and ‘Good’ otherwise.

QUESTION
I faced a problem during the next use case.
...ANSWER
Answered 2018-Nov-06 at 11:56Your deleted / changed text is less than one line, so it will be moved into the small delete register (:help quote-
), and nowhere else. Numbered registers (where you probably expected the changes) are only automatically filled with text longer than one line. From :help quote_number
:
Numbered register 1 contains the text deleted by the most recent delete or change command, unless the command specified another register or the text is less than one line (the small delete register is used then). An exception is made for the delete operator with these movement commands: %, (, ), `, /, ?, n, N, { and }.
So, if you want to keep the small delete, you need to explicitly specify a register for all [but the last] change or delete. For example: "acaw
["1
]daw

...ANSWER
Answered 2017-Apr-20 at 15:24The stack trace suggests that the rc
module is causing the error.
That module is used by a module called get-proxy
to determine if there are any HTTP/HTTPS proxies configured. It's trying to read the NPM configuration, which is typically stored in a file called ~/.npmrc
The error suggests there's an issue with that file.
